| Abstract: |
Measuring the percentage composition of individual pulps in a blended furnish usually involves tedious fiber counting techniques. Furnishes with two components can use an optical fiber-length analyzer. This paper presents a general mathematical techniques for expressing the fiber length averages of distributions obtained this way. This technique permits the derivation of accurate mathematical relationships between pulp component percentages and all fiber length averages-arithmetic, length-weighted, or weigh-weighted. The derived relations also have use with three or more components.

| Applications: |
A mathematical technique allows calculation of instantaneous pulp component percentages of rapidly changing pulp blends with on-line fiber length analyzers.
